My beloved ordered this hat for our trip to Tahoe in February, exactly a week before we headed out. We found a free pattern on Ravelry that we both thought would work. Then I knitted, ripped, knitted some more, ripped some more. Casted off around Sacramento (about an hour away from the snow), so he had a hat to wear and not catch a cold when they played, but it was a tad small. Final version was finished the night before we headed back. All in all, I knitted more than three hats in less than a week.
Pattern: Jacques Cousteau Hat, heavily modified on number of stitches, ribbing, decrease, but the idea is the same
